How dangerous is seasonal flu?
Seasonal flu is an acute respiratory infection caused by influenza virus. The disease often appears in winter and spring, when the body cannot respond to changes in weather. If the patient is not treated early and properly, dangerous complications can occur.Changing weather and erratic sunshine and rain are the times when the incidence of influenza increases, causing many serious health consequences. A person infected with flu is sure to spread it to everyone in the family, to colleagues, neighbors, and relatives. The consequences of flu cause superinfection, respiratory infections (pharyngitis, sinusitis, bronchopneumonia,...) and even types of flu that cause complications like myocarditis and conjunctivitis. Prolonged flu causes many health problems (memory loss, seizure disorder,...)
EMIN Deploys seasonal flu vaccination for employees
This morning, August 6, 2024, EMIN Vietnam Joint Stock Company organized seasonal flu vaccination for employees in the Hanoi area. Below are some notable images:
A VLF very low frequency AC voltage tester is used to assess the insulation condition of cables, transformers, and certain high-voltage electrical equipment. The equipment generates AC test voltage at a very low frequency, typically in the range of 0.05 Hz to 0.1 Hz as referenced in technical sources. This method is particularly useful for testing capacitive loads, such as power cables and certain high-voltage equipment.
Insulation oil testing helps detect changes associated with aging, moisture, and contaminants in the oil. Combining a suitable insulation oil tester with careful sampling procedures and regular data monitoring supports proactive maintenance of electrical equipment and helps maintain the required insulation condition during operation.
The protective relay test set generates controlled current, voltage, and phase-angle signals to evaluate the relay's response under defined conditions, helping improve the reliability of power system operation.
A megohmmeter must be used according to the proper procedure to ensure operator safety and reliable measurement results. This article covers its operating principle, testing procedure, influencing factors, and essential safety precautions.
A ground resistance tester is used to measure the resistance of a grounding system or ground electrode. Using the correct measurement method gives operators a better basis for identifying changes in the system over time and taking appropriate inspection or corrective measures.
